Permits and Zoning in Mundelein

Additions in Mundelein require a permit and zoning review from the Village of Mundelein for setbacks and lot coverage. We confirm what applies and manage the full process.

The Right Approach For Your Mundelein Home Addition

Whether you need to add extra room for a growing family or a second level to your home, our team will help you find the best way to expand your space.

Single Level Additions

If you find yourself needing more living space and want to expand your home rather than upsize, a single-level addition is the place to start.

The most cost-effective way to add living space, a single-level addition attaches to the side of the home. They typically require expanding the home’s foundation, and are most often used for expanding kitchens, living rooms, or home offices.

Single-level additions are typically limited by lot size and setback laws. For this reason, these additions are better fit for homes on larger lots.

Second Story Additions

Want to expand your home without expanding its footprint? Many homeowners don’t realize it’s possible to expand their living space by adding a second story.

Although often more expensive than single-level additions, second-story additions can be a great solution for homeowners who need additional living space but don’t have enough yard space to build out.

Second-story additions tend to be more technically challenging, as they require extensive engineering and planning to ensure that they don’t disrupt the design or aesthetic of the existing structure.

Basement Additions

For some homeowners, a basement addition is the best way to expand their living space. This often involves either raising the home or digging out the crawl space.

Homeowners who go this route often use their basement for additional bedrooms, a recreational space, or an Accessory Dwelling Unit (ADU).

Basement additions are among the most expensive methods of adding onto a home. Extensive manual labor, planning, and permitting all contribute to the high cost of basement additions.
